Evidence for Hierarchical Predictions in the Human Visual Cortex
Using high-resolution fMRI, we show that prediction errors propagate up the cortical hierarchy while predictions flow downward, supporting predictive processing theory.
Paper added: Precision-Weighted Prediction Errors
Precision Weighting of Cortical Prediction Errors
We demonstrate that the brain weights prediction errors by their precision (inverse variance), explaining how attention modulates perceptual inference under predictive processing.
Controversy: Is predictive processing falsifiable?
Critics argue the theory is too flexible to make concrete predictions. Defenders respond with specific experimental paradigms.
Predictive Processing: A Critical Assessment
We address criticisms of predictive processing as unfalsifiable. We outline specific experimental predictions that distinguish predictive processing from alternative frameworks, including precise timing of neural responses and cross-modal integration patterns.

The Free-Energy Principle: A Unified Brain Theory?
This paper introduces a free-energy principle for biological systems, suggesting that all adaptive systems minimize variational free energy. This provides a unified account of perception, action, and learning.
